Patent number: 11608017Abstract: A vehicle front body structure is provided for reliably transferring a collision load to a crash can and a front frame by preventing a bumper beam from buckling during a small overlap collision. Bending rigidity of the bumper beam in a vehicle width direction is such that 1) a bending moment generated on the bumper beam when a collision load in a direction toward a vehicle rear side is applied to an extending section, which extends outward in the vehicle width direction from a crash can fixed section, is the highest in a vehicle width direction inner end portion of the crash can fixed section on a side where the collision load is applied, and 2) the bending moment is continuously reduced as a distance from the vehicle width direction inner end portion in the vehicle width direction increases.Type: GrantFiled: June 23, 2021Date of Patent: March 21, 2023Assignee: MAZDA MOTOR CORPORATIONInventors: Takashi Narahara, Nobuyuki Shibutake, Yasushi Ishikawa, Yuichi Morita, Ken Fujimoto, Yusaku Yamaguchi

Patent number: 11548558Abstract: A front vehicle-body structure comprises a crash can fixed to a front end of a front frame. The crash can comprises an upper face portion, a lower face portion, a pair of side face portions, corner portions respectively positioned between the side face portion and the upper face portion and between the side face portion and the lower face portion, a first fragile portion provided at each of the corner portions, and a second fragile portion provided at each of the side face portions. The first fragile portion is configured to be deformed before the second fragile portion when a collision load applied toward a vehicle rearward side is inputted to an extension portion of a bumper beam. The second fragile portion is configured to be deformed before the front frame when the collision load applied toward the vehicle rearward side is inputted to the extension portion.Type: GrantFiled: April 15, 2021Date of Patent: January 10, 2023Assignee: MAZDA MOTOR CORPORATIONInventors: Takashi Narahara, Nobuyuki Shibutake, Yasushi Ishikawa, Yuichi Morita

Patent number: 10358175Abstract: A deflector structure of an automobile includes: a liner extended portion covering a lower-surface opening located at a front side of a wheel housing; and a deflector attached to the liner extended portion. The deflector is integrally configured by: a deflector base portion attached to the liner extended portion through a bolt and a resin clip; and a plate-shaped deflector main body extending from a rear end of the deflector base portion to a vehicle lower side and having flexibility and a thickness in a forward/rearward direction. A plurality of rear-surface ribs each extending in an upward/downward direction are formed on a rear surface of the deflector main body at predetermined intervals in a width direction, upper ends of the rear-surface ribs being in contact with a lower surface of the liner extended portion.Type: GrantFiled: October 6, 2016Date of Patent: July 23, 2019Assignee: Mazda Motor CorporationInventors: Nobuyuki Shibutake, Koji Yoshitake, Nobuyuki Nakayama, Takashi Fukumaru

Patent number: 10124838Abstract: A deflector comprises a protrusion portion which protrudes downward, including a slant face portion slanting obliquely rearward and downward, and a vertical wall portion which is provided in back of the protrusion portion to extend in a vehicle width direction. A lower end portion of the vertical wall portion is positioned at a lower level than a rear end portion of the slant face portion. The lower end portion of part of the vertical wall portion located inward from the other part of the vertical wall portion located so as to overlap the front wheel in a front view is positioned at a higher level than the lower end portion of the other part of the vertical wall portion located so as to overlap the front wheel in the front view.Type: GrantFiled: May 13, 2016Date of Patent: November 13, 2018Assignee: MAZDA MOTOR CORPORATIONInventors: Nobuyuki Shibutake, Nobuyuki Nakayama, Koji Yoshitake, Akihiro Kawano, Masafumi Aburame
